"With the Samsung Galaxy S4 presumably coming soon, many are excited about the possibility of running a more stock Android-based experience, like CyanogenMod, on the hardware. It looks like that's going to be a slower transition than many were hoping, as the current Samsung CM maintainers have said that they have no plans to support the device." If you like custom ROMs, don't buy Samsung. As simple as that.

I was not aware of such shenanigans. Although they are kind of minor, It would be nice if someone actually had the bankroll and sufficient attitude to actually sue them for the violations that crop up. It kind of seems like they are more incompetent at providing source than malicious.

You're assuming they actually have the source for that build tagged and stored as such.

I'm not assuming that they do. If they do then either they just suck at following through on the request, or they really are trying to hide small modifications that they've made in those builds for what ever reasons ( binary modules making use of GPL ONLY Interface? compiled no GPL module directly into kernel?, Embarrassed about the off color language embedded into variable names? Embarrassed about the code quality? )
